This project concerns syntactically annotating texts written by
learners of English as a second language. Our goal is to annotate
linguistic properties present in a given sentence, without making
too much interpretation about what the learner meant to say, or what
the correct form should have been. To acheive this end, our
annotation scheme adds several pieces of linguistic information
about each word, based on its context in the sentence, and based on
the rules of English (the target language). We annotate dependency
relations to mark syntactic relations between words in a
sentence - e.g., one word is the subject of another word.

This site is under development, so please be patient.

Researchers

Resources

A beta version of the guidelines we are using are available here. It should be noted that these guidelines are still in progress, and we welcome feedback. We are releasing this version of the guidelines, before any data is released, because we feel that they will be useful to other researchers. The decisions we have made (certainly needing refinement in some cases) point out many of the essential questions that need to be addressed for linguistically annotating learner data, and we hope they can stimulate discussion.
